This paper describes a mathod for the determination of arsenic in lead ingots with a flow injection quartz tube atomic absorption spectrometry. 采用流动注射石英管原子吸收法测定铅锭中痕量砷。
Atomic Absorption Spectrometric Determination of Arsenic in Steel and Geological Samples Using Hydride Generation Combined with Slotted Tube Atom-trap Technique 氢化物发生-缝管原子捕集-原子吸收法测定钢铁和地质试样中的砷
Fluorescence measurement is based on the reduction of arsenic by potassium borohydride and introduction of its gaseous hydride into the electrically heated silica tube. 荧光测量是建立在用硼氢化钾还原砷,并将砷的气体氢化物导入电加热石英管中原子化的基础上。
Arsenic passes through the placenta and accumulates in the neuroepithelium of embryo, whereby inducing congenital malformations such as neural tube defects ( NTDs) in animals. 砷可通过胎盘在动物胚胎的神经上皮蓄积,从而诱导先天性畸形,如神经管畸形(NTDs)等。
